Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors, and particularly relates to an anti-icing structure for a turbocharger. Background Technique

[0002] A turbocharger is a device used to increase the pressure of a gas or liquid medium. In actual use, the turbocharger is located at the front end of the engine intake system. At the same time, there is throttling at the compressor inlet, and supercooled water droplets are likely to deposit and freeze at the compressor inlet. When the compressor inlet freezes, ice slag enters the compressor and collides with the impeller, causing damage to the turbocharger and even aircraft crashes. The existing anti-icing structures of turbochargers only melt the ice slag through the filtered exhaust gas and the compressor air inlet heated by the exhaust gas. This heating method has a low efficiency in melting the ice slag. Moreover, the existing anti-icing structures of turbochargers need to filter the exhaust gas. When the user replaces the filter element, several screws need to be installed, resulting in the reduction of the user's efficiency in replacing the filter element. Content of the Utility Model

[0021] Please refer to Figures 1-6 , the present utility model provides the following technical solutions: An anti-icing structure for a turbocharger, including a main body 1, a return pipe 2, a heating pipe 4 and an air delivery pipe 5, further including a filter mechanism 3, a grille 6 and a fixing mechanism 7. An exhaust gas exhaust pipe 11 and a compressor air inlet 13 are respectively arranged on two sides of the main body 1. A wide-mouth pipe 12 is arranged on the compressor air inlet 13. A grille 6 is arranged on the wide-mouth pipe 12. A heating pipe 4 is wound outside the compressor air inlet 13. The heating pipe 4 is connected to the exhaust gas exhaust pipe 11 through the return pipe 2. An air delivery groove 63 is arranged inside the grille 6. The air delivery groove 63 is connected to the heating pipe 4 through the air delivery pipe 5. A placing barrel 32 is arranged on the return pipe 2. An arc-shaped cover 31 is hinged on the side wall of the placing barrel 32. A fixing block 33 and a fixing groove 34 which are matched with each other are respectively arranged on the arc-shaped cover 31 and the placing barrel 32 when they rise. A filter element 35 is arranged inside the placing barrel 32. A fixing mechanism 7 is arranged on the fixing groove 34;

[0022] The fixing mechanism 7 includes a screw 71, a top block 72, a T-shaped groove 73, a locking block 74 and a connecting rod 75. A screw 71 is arranged on the fixing groove 34. The top block 72 is installed on the screw 71. Several T-shaped grooves 73 are arranged on the inclined surface of the locking block 74. The top block 72 is slidably installed in the T-shaped groove 73 through the side wall protrusion. A groove which is matched with the side wall protrusion of the locking block 74 is arranged on the side wall of the fixing block 33. Several connecting rods 75 are arranged on the side wall of the fixing groove 34. The locking block 74 is slidably installed on the connecting rods 75.

[0023] The exhaust gas pipe 11 is used to discharge exhaust gas. The compressor air inlet 13 is used to supply outside air into the interior of the main body 1. The wide-mouth pipe 12 increases the intake area of the compressor air inlet 13. The return pipe 2 is used to convey exhaust gas. The filtering mechanism 3 is used to filter the exhaust gas in the return pipe 2. The filter element 35 is used to filter exhaust gas. The groove provided on the side wall of the placement barrel 32 and cooperating with the arc-shaped cover 31 is used for the user to install and disassemble the filter element 35. During the use of the filtering mechanism 3, the fixing block 33 enters the interior of the fixing groove 34, and the fixing block 33 is fixed on the fixing groove 34 through the fixing mechanism 7, thereby ensuring the stability of the arc-shaped cover 31 during the use of the device. The exhaust gas discharged from the exhaust gas pipe 11 enters the interior of the heating pipe 4 through the return pipe 2 and the filtering mechanism 3. The heating pipe 4 with exhaust gas flowing through it will heat the compressor air inlet 13 to prevent ice slag from entering the interior of the main body 1. The exhaust gas entering the interior of the heating pipe 4 enters the interior of the air delivery groove 63 through the air delivery pipe 5. The air entering the interior of the air delivery groove 63 will heat the grille 6. The grille 6 can intercept ice slag. When the ice slag contacts the grille 6, the heated grille 6 can melt the ice slag to prevent ice slag from entering the interior of the main body 1. The grille 6 can prevent a large amount of ice slag from entering the compressor air inlet 13 simultaneously at one time, preventing the device from being unable to quickly melt all the ice slag, and ensuring the working effects of the heating pipe 4 and the grille 6;

[0024] The screw 71 is rotatably installed on the fixing groove 34, and the top block 72 is installed on the screw 71 through threads. When the user rotates the screw 71, the top block 72 moves along the screw 71 under the action of the threads. The shapes of the side walls of the top block 72 and the locking block 74 in contact are mating inclined surfaces. When the top block 72 moves, the locking block 74 starts to move under the pushing of the top block 72. When the locking block 74 moves, the side wall protrusion of the locking block 74 enters the interior of the side wall groove of the fixing block 33, thereby realizing the fixing of the fixing block 33 by the fixing mechanism 7. The locking block 74 is slidably installed on the connecting rod 75 to ensure the stability of the locking block 74 during the moving process. By providing several connecting rods 75, the working effect of the connecting rods 75 is ensured. The locking block 74 is connected together through the cooperation of the T-shaped groove 73 and the inclined surface protrusion of the top block 72. The shape of the T-shaped groove 73 ensures that when the top block 72 moves in any direction, the top block 72 can drive the locking block 74 to move together. By providing several T-shaped grooves 73, the stability of the cooperation between the top block 72 and the locking block 74 is ensured.

[0025] Specifically, several exhaust holes 62 are provided on the side wall of the blade of the grille 6, and filter meshes are provided on the exhaust holes 62.

[0026] After the filtered waste gas enters the gas transmission tank 63, the waste gas will enter the interior of the main body 1 through the exhaust holes 62. The waste gas leaving the grille 6 will heat the ice slag, improving the efficiency of the device in melting the ice slag. The exhaust holes 62 provided on the blades allow air to flow, reducing the influence of the grille 6 on air flow. The filter net provided on the exhaust holes 62 serves to block the ice slag, preventing the ice slag from entering the interior of the main body 1 through the exhaust holes 62 and ensuring the working effect of the grille 6.

[0027] Specifically, the shape of the blades of the grille 6 is arc-shaped, and the front end of the blades of the grille 6 and the rear end of the adjacent blades are in the same vertical plane.

[0028] The shape of the blades of the grille 6 increases the side wall area of the blades, improving the working effect of the grille 6 in blocking the ice slag. The positions where the two ends of the blades of the grille 6 are located can prevent the ice slag from directly passing through the grille 6 without being intercepted, ensuring the working effect of the grille 6.

[0029] Specifically, a conical block 61 is provided in the center of the grille 6, and the shape of the front end of the blades of the grille 6 is an inclined plane that slopes towards both sides of the blade.

[0030] The shapes of the conical block 61 and the front end of the blades of the grille 6 play a guiding role, preventing the ice slag from accumulating on the grille 6 and improving the efficiency of the device in melting the ice slag.

[0031] Specifically, protrusions are provided on the side wall of the top block 72, grooves matching the protrusions on the side wall of the top block 72 are provided on the side wall of the fixing groove 34, and a support rod passing through the protrusions on the side wall of the top block 72 is provided on the fixing groove 34.

[0032] The cooperation between the protrusions on the side wall of the top block 72 and the matching grooves plays a limiting role, preventing the top block 72 from detaching from the screw 71 during the process of the user rotating the screw 71, ensuring the stability of the top block 72 during the use of the device. The support rod passing through the top block 72 plays a guiding role, ensuring the stability of the top block 72 during the moving process. The support rod passing through the top block 72 also plays a limiting role, preventing the top block 72 from being rotated by the screw 71, ensuring the working effect of the top block 72.

[0033] Specifically, protrusions are provided at the top end of the connecting rod 75, and grooves matching the protrusions at the top end of the connecting rod 75 are provided on the side wall of the groove for installing the connecting rod 75.

[0034] The cooperation between the protrusions at the top end of the connecting rod 75 and the matching grooves plays a limiting role, preventing the locking block 74 from detaching from the connecting rod 75 during the moving process, ensuring the stability of the locking block 74 during the use of the device.

[0035] Specifically, a sealing gasket is provided on the side wall where the arc-shaped cover 31 contacts the placement bucket 32.

[0036] The gasket provided on the arc-shaped cover 31 and the placement barrel 32 can seal the gap between the arc-shaped cover 31 and the placement barrel 32, preventing waste gas from leaking through the gap between the arc-shaped cover 31 and the placement barrel 32 during the use of the device, and ensuring the working effect of the filtering mechanism 3.

[0037] The working principle and usage process of the present utility model: When the device is in use, waste gas is discharged from the main body 1 through the waste gas exhaust pipe 11. During the process of discharging the waste gas, the waste gas enters the return pipe 2. The waste gas entering the return pipe 2 is filtered by the filtering mechanism 3 and then enters the heating pipe 4. Subsequently, the filtered waste gas enters the air delivery groove 63 through the air delivery pipe 5, and finally the waste gas enters the wide-mouth pipe 12 through the exhaust hole 62. The compressor air inlet 13, the grille 6, and the heating pipe 4 are heated under the action of the waste gas. When the device is in use, external air passes through the grille 6 and the exhaust hole 62 and then enters the interior of the main body 1 through the wide-mouth pipe 12 and the compressor air inlet 13. The ice slag in the air contacts the blades of the grille 6 during the air flow process, and the heated blades will melt the ice slag. The ice slag that cannot be completely melted will be melted by the filtered waste gas and the heated compressor air inlet 13. When replacing the filter element 35, rotate the screw 71. The top block 72 moves along the screw 71 under the action of the thread. The locking block 74 is driven by the moving top block 72 to move under the action of the T-shaped groove 73 and the matching protrusion. The moving locking block 74 disengages from the matching groove on the fixing block 33, and the fixing of the fixing block 33 is released. Separate the arc-shaped cover 31 and the placement barrel 32, remove the old filter element 35 from the placement barrel 32, install the new filter element 35 on the placement barrel 32, rotate the arc-shaped cover 31 to make the fixing block 33 enter the fixing groove 34, and reverse-rotate the screw 71. The top block 72 moves in the reverse direction. As the top block 72 moves, the locking block 74 enters the matching groove on the fixing block 33 that matches the locking block 74, and the fixing block 33 is fixed.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
